Because we end up with VIEW_CONVERT_EXPRs in places where we do not want them.
lto1: internal compiler error: in remap_decls, at tree-inline.c:576
internal compiler error: tree check: expected tree that contains 'decl common'
structure, have 'view_convert_expr' in remap_decls, at tree-inline.c:542
internal compiler error: tree check: expected tree that contains 'decl common'
structure, have 'view_convert_expr' in remove_unused_scope_block_p, at
tree-ssa-live.c:450
Breaks 200.sixtrack and 191.fma3d.

It's not exactly clear how to avoid this the easies - probably keeping some state what we are walking in lto_fixup_*. In theory we'd only need to fixup the decl pointers in the reader cache so reading of the IL will pickup the VIEW_CONVERT_EXPRs. -- rguenth at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- AssignedTo|unassigned at gcc dot gnu |rguenth at gcc dot gnu dot |dot org |org Status|UNCONFIRMED |ASSIGNED Ever Confirmed|0 |1 Last reconfirmed|0000-00-00 00:00:00 |2009-10-15 12:41:57 date| | http://gcc.gnu.org/bugzilla/show_bug.cgi?id=41715 ^ permalink raw reply [flat|nested] 4+ messages in thread
